Thanks, the code was correct when written but the world has moved on!
Is your adapter transmitting packets successfully now?
It's working really well. I'm using David du Colombier's nat patch
(I'll post to the list another one without the il stuff in case
someone wants to try it) to share internet to a linux machine, so
I made a test from the browser (speedtest.net) and almost reached
the contracted limit of my fiber connection, although I only have
a crappy 100Mb plan (I don't really need more). So packets are
flowing, but when plan9 is more involved things get worse.
For example with this setup (a small arm linux machine connected
through plan9, using the usb adapter for internet):
linux:
$ wget -O /dev/null
https://arch.mirror.constant.com/images/v20220801.71902/Arch-Linux-x86_64-basic-20220801.71902.qcow2
[...]
/dev/null 100%[===================>] 489.88M 10.5MB/s in 51s
2022-08-02 22:56:44 (9.58 MB/s) - ???/dev/null??? saved [513671168/513671168]
real 0m51.875s
user 0m8.594s
sys 0m5.379s
And the progress bar saw me several times the speed reaching my
limit. So the usb and ethernet drivers seem to be working pretty
good (at least for my bandwidth)
plan9:
; time hget -o /dev/null
https://arch.mirror.constant.com/images/v20220801.71902/Arch-Linux-x86_64-basic-20220801.71902.qcow2
couldn't set mtime: permission denied
8.06u 35.25s 211.17r hget -o /dev/null

See the difference? That's a little more than 19Mb/s, some 2MiB/s almost 50%
slower.
By the way I don't use archlinux but I've always use their servers
to make speed tests, usually they are fast.
Actually the limit on maxpkt in that context wasn't strictly necessary anyway.
Just remove the check.
Yes, I thought the same.
